Officers were in the Great Holm area when they were flagged down about a stolen vehicle.
In a post on Facebook, Thames Valley Police said: "2 males made off from Police and were quickly apprehended near to Lodge Lake, Great Holm.
"A massive thank you to the member of the public that offered to help!
"Both riders were given a Section 59 and bikes seized and crushed!"
Riders are given a section 59 when an officer has reasonable grounds for believing that a motor vehicle is being used without due care and attention.
